• It allows to create some objects to simplify some calculations (see example).
• It also provides some common Math formulas in Physics.

Which formulas are contained?

Classical mechanics

• Force, Speed, Time, Work, Acceleration, Density, Intensity, Power, Momentum
• Potential Energy, Mechanical Energy, Kinetic Energy, Frequency, Doppler Effect
• Centripetal Acceleration, Centripetal Force, Pendulum Period, Projectile motion equations

Gravity

• Potential Gravitational Energy, Universal Gravitational Law, Gravitational Field
• Escape Speed

Fluids

• Stokes's Law, Hagen-Poiseuille's Law

ElectroMagnetism

• Ohm's Law, Capacitance, Voltage, Coulomb's Law, Energy Density
• Electric Field, Eletric Potential Energy Difference.

Termodynamics

• Gay-Lussac's Law, Net Heat Energy, Heat Flux, Eletric Field Flux, Joule Heating

Relativity

• Lorentz Factor, Relativistic Time, Relativistic Distance, Relativstic Mass, Relativistic Momentum
• Photoelettric Effect, Drift Speed.

How to use it

• Download the 'formulas' package to get the Physics formulas:

go get -u github.com/Gabri432/gophysics/formulas

• Download the 'constants' package to get the Physics constants:

go get -u github.com/Gabri432/gophysics/constants

• Download the 'mathem' package to get the Mathematical functions and constants of the library

go get -u github.com/Gabri432/gophysics/mathem

• Example of usage

package main

import (
    "fmt"
    "github.com/Gabri432/gophysics/constants"
    "github.com/Gabri432/gophysics/formulas"
)

func main() {
    fmt.Println(constants.C)   // Write a constant
    fmt.Println(formulas.Force(3, 4))   // Call a function
    myPlanet := formulas.PlanetBody{Mass: constants.EARTH_MASS, Radius: constants.EARTH_RADIUS} // Create a custom object
	fmt.Println(myPlanet.EscapeSpeed())  // Call object methods to ease some calculations
}

=== Output ===
299792453  
12 N       <<< When calling functions their output is the value and the measurement unit
11183.719071923773 m/s

• Using mathematical functions

import (
    "fmt"
    "github.com/Gabri432/gophysics/mathem"
)

func main() {
    fmt.Println(mathem.Pi) // Writing a constant
}

=== Output ===
3.1415926535

Documentation

Overview

A package that provides different functions and constants for making some of the most common calculation in Physics.

Classical Physics, Gravity, Fluids, Termodynamics, Electromagnetism, Relativity are for now the covered areas.

As so this package does not claim to be the most extensive or the best one, but it is thought as a useful tool for the most common cases.

Formulas were taken from this italian book: Title - "Fisica Volume 1", Authors - ["P. Mazzoldi", "M. Nigro", "C. Voci"].
